土质边坡锚柱板支护系统设计新方法

A New Design Method for Anchor Pillar and Plate Supporting System of Soil Landhill

利用土质边坡破坏的断面形式近似圆弧形的特点,采用瑞典圆弧分析法,充分利用计算机迭代搜索功能,对每一搜索出的滑面计算其安全系数,从而找出潜在的最危险(安全系数最小)的滑动面,依据此滑面来计算锚杆、肋柱及面板的内力,设计支护系统其它各参数。

In this paper, a new approach, 'Sweden arc sliding method', is used to find the most (dangerous) sliding surface whose safety factor is the least by computer continually searching all potential sliding (surfaces) and calculating safety factors. According to it, once pressure on anchor、 pillar and plane has been (calculated), then the other internal forces and parameters will be easily determined.
